Run Script in multiple versions simultaniously

[Pallavi]

I have 10 tests in a quality center testset. I need to run these 10 tests in 2 versions of application.
Environment.xls contains the host system name and the application versions.
System1 has application version1
system2 has application version2

So the tests should pick the system name and version number from this sheet and run on that particular host system.

I mean the first test in the testset should read the host system from xls file say system1 which has version1 and execute on that system
Then it has to read the next system name from xls file which contains version2 and execute again on the second system.

Please let me know if it is possible to do this.

Thanks and Regards,
Pallavi
